A new study has documented one picture's flight of almost 220 miles over Alabama and Tennessee in 2011. That is among the longest-documented trajectories of tornado debris, the researchers found. Reported WBIR
The photo was among 934 objects in a database built by University of Georgia associate professor John Knox and his students. They say the research could aid public safety by predicting where tornado-borne toxic or radioactive debris might fall.
The research relied heavily on a Facebook page created by an Alabama woman, who posted pictures of the debris. Tolong Share ya ^^
